地层标志层对钻探生产的指导作用探讨——以山东滕县煤田田陈煤矿为例

On the Guidance of Stratigraphic Marker on Drilling Production-A case study of Tianchen Coal Mine

田陈煤矿地层自老而新有奥陶系、石炭系、二叠系、侏罗系和第四系等,地层标志层主要有太原组第十四层石灰岩、太原组第十下石灰岩、太原组第三层石灰岩、侏罗纪砾岩、3下煤层及其与其他标志层的间距等。其中侏罗纪砾岩和3下煤层及其与其他标志层的间距对煤矿补勘阶段钻探生产具有重要的意义。

Tianchen coal strata from the old and the new is composed of the ordovician, carboniferous, Permian and Jurassic and the quaternary stratigraphic strata. And its strata marker mainly has the 14th layers of limestone, the 10th limestone, the third layer of limestone, Jurassic conglomerate, 3 coal seam and the other logo layer spacing, etc. Particularly, the distance between Jurassic conglomerate and 3 lower coal seam is of great signifcance to the drilling and production of coal mining.
